Although pathology reports of thyroid tissue in ovarian teratomas are abundant, benign teratomas of the thyroid are extremely rare in adolescents and adults. Therefore, their clinical characteristics are still not well characterized. We report a case of a 54-year-old woman with a growing mass in her neck. Left lobectomy of the thyroid revealed it to be a benign thyroid teratoma composed of tissues from all three germ layers. Preoperative evaluations included thyroid ultrasonography (US), ultrasound-guided fine needle aspiration cytology (FNAC), and computed tomography (CT) of the neck. A 4.7-cm, well defined, predominantly hypoechoic mass intermingled with hyperechoic internal lesions, was observed in the inferior portion of the left thyroid lobe with substernal extension on US. The posterior extent of the nodule was not visualized due to deep attenuation of the echo. US-guided FNAC failed to reveal any thyroid follicular cells, but suggested a benign cystic tumor. Neck CT hinted at the diagnosis of teratoma because the mass contained large amounts of fat, and the margin was well defined. Extrathyroidal extension and cervical lymphadenopathy were not seen. She underwent left thyroid lobectomy, and histologic examination confirmed benign thyroid teratoma. To the best of our knowledge, this is the first case report of benign thyroid teratoma in Korea.

Abstract PDF

Teratoma is a congenital tumor containing tissues derived from all germ layers. Teratoma in the region of the adrenal gland is a very uncommon retroperitoneal tumor. Only 7 cases of adrenal teratoma have been reported worldwide, but in Korea, no similar cases have been reported until now. This case report describes an adrenal teratoma in a 38-year-old healthy woman who was incidentally diagnosed with a left adrenal mass on abdominal ultrasonography during a medical inspection. Computed tomographic scans revealed a 9-cm heterogeneous circumscribed round mass, containing primarily fat tissue, and a solid calcification component in the left adrenal gland. Adrenal hormonal assessment results and biochemical markers for gonadal neoplasia were negative. Result of serum laboratory tests were normal. The patient underwent laparoscopic adrenalectomy. Histologic analysis confirmed the diagnosis of a mature teratoma; the obtained specimen measured 5 x 7 x 7.5 cm and weighed 267 g. The surface of the mass was smooth, and sebaceous tissue and hair with hard material were observed on the incisional surface. The patient was discharged on postoperative day 4, without complications. In this case report, we describe the incidental finding of a teratoma occurring in the adrenal gland region in a healthy woman; the teratoma was laparoscopically excised.
